Since each of the star-shaped filler 5 has a form whose convex part fits into a concave part of another, a region filled with the filler in high density can be formed. The radiation 7 is attenuated by a shield filler 5c in an external space 3. Then, the radiation attenuated in this way enters the internal space 2 after passing through an outer shell 19. In the internal space 2, the intensity or quantity of the radiation 7 is attenuated by the region filled with the star-shaped filler 5 in high density as the radiation 7 goes toward the electronic parts 4.
